Managing Rate Risk on a Variable Mortgage

A variable-rate mortgage moves with the Bank of Canada's policy rate — your payment (or how much of it goes to interest, depending on your lender's structure) can rise without warning between rate announcements, unlike a fixed rate that's locked for your full term.

A practical way to manage this: stress-test your own budget against a rate a point or two higher than your current one, not just the federal stress test rate you originally qualified at. If a realistic increase would genuinely strain your budget, that's worth knowing before it happens, not after.

Building a buffer — even a modest one — specifically earmarked for a potential payment increase gives you room to absorb a rate rise without immediate financial stress, rather than discovering the gap in real time.

Most variable-rate mortgages allow converting to a fixed rate at any point during your term without the penalty typically associated with fully breaking a mortgage — worth knowing as an option if your risk tolerance changes partway through your term, even if you don't plan to use it.
